Behold: the biggest bangs we’re allowed to offer for sale. And you’re sure to get plenty of bang for your buck when you invest in Ammo Inc., which loads high-quality materiel for anti-materiel rifles in Manitowoc, Wisconsin.

This cartridge is loaded with a 660 grain full metal jacket projectile. Ammo Inc. has not published the cartridge’s ballistic data, though it’s reasonable to assume its muzzle velocity was recorded with a 36” barrel. We also surmise its G1 BC to be approximately .700 (though we haven’t confirmed as much through actual chronographic testing). If we’re not too far off the money, then velocity stays supersonic until 1,800 yards or so.

This is not military surplus ammunition. It was specifically loaded for the commercial market, and recently, and features noncorrosive Boxer-style primers, virgin reloadable brass cases, and the manufacturer’s appropriately named HyperClean Technology propellant. Five boxes per case.
